Sepax Technologies Inc Sepax HPLC Column Proteomix WAX, NP1.7, Guard cartridge with holder, 2 x 10 mm
Sepax HPLC Column Proteomix WAX, NP1.7, Guard cartridge with holder, 2 x 10 mm
Sepax Technologies Inc Sepax HPLC Column PolyRP-500, Guard cartridge with holder, 10 µm, 2 x 10 mm
GP-C8 phase is synthesized with monomeric and fully endcapped chemistry. The uniform octyl stationary phase allows high efficiency with lower hydrophobicity compared to ODS phase. GP-C8 phase is suitable for separating compounds with a wide range of hydrophobicity. It is highly recommended for separating the compounds which are too strongly retained on C18 phases.

Waters Corp SunFire C18 Sentry Guard Cartridge, 100Å, 5 µm, 2.1 mm X 10 mm, 2/pk
SunFire C18 columns are used for general purpose method development at low pH. The C18 ligand is highly retentive, especially for basic compounds and it is ideally suited for purification and impurity profile assays.
Mac-Mod Avantor Prevail C8, 110 Å, 5 µm, 4.6 x 7.5 mm Guard Cartridges (3/pk)
Avantor Prevail HPLC columns exhibit long column lifetime in both highly aqueous and highly organic mobile phases. Avantor Prevail HPLC columns are silica based except for Prevail Carbohydrate ES. The stability of these phases is such that a single column can be switched between highly aqueous for analysis of highly polar analytes and highly organic for strong retention of hydrophobic analytes. Avantor Prevail HPLC columns are stable from highly organic to highly aqueous. Avantor Prevail HPLC columns are specialty phases for specific applications. Avantor Prevail HPLC columns provide excellent sensitivity with microbore and ELSD applications.

Sepax Technologies Inc Sepax HPLC Column Proteomix WCX, NP3, 4 x 10 mm
Proteomix ion-exchange phases have been innovatively developed for achieving high ion-exchange capacity, a breakthrough technology for non-porous resins. Proteomix packing support is composed of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) non-porous bead with particle size selections of 1.7, 3, 5 and 10 µm. The PS/DVB resin surface is grafted with a highly hydrophilic, neutral polymer thin layer with the thickness in the range of nanometer. The hydrophobic PS/DVB resin surface is totally covered by a hydrophilic coating that eliminates non-specific bindings with biological analytes, leading to high efficiency and high recovery separations for biological molecules.
